CUTTING APPARATUS FOR HARV ESTERS.

SPECIFICATION forming part of Letters Patent No. 344,191, dated June 22,1886.

Application filed April 23, 1885.

To aZZ whom it may concern:

Be it known that I, LACY MCSIPPLE, a citizen of the United States ofAmerica, residing at Bucklin, in the county of Linn and State ofMissouri, have invented certain new and useful Improvements in CuttingApparatus for Harvesters; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to cutting apparatus for harvesters; and itconsists in theimprove- 'ments hereinafter described and set forth.

In the accompanying drawings, Figure l is a plan view of a harvesterhaving my improvements. Fig. 2 is a perspective view of the guardshoe.Fig. 3 is a perspective view of one end of the cutter-bar. Fig. 4 is atransverse section through the pitman-connection with the cutter-bar;and Fig. 5 is a detail perspective view of the devices employed forconnecting the end of the pitman with the driving mechanism.

In a suitable frame composed of the barsA B are journaled parallelshafts, one of which, 0, projects beyond the sides of the frame, topermit the carrying-wheels to be keyed thereon, and thereby impartmotion thereto. This said shaft 0 is provided within the frame withparallel gear-wheels a b, each of which meshes with pinions c d, keyedon the parallel shaft D. A bevel gear-wheel, E, is mounted on the saidshaft D, and is provided with a collar having a series of ratchet-teeth,6, designed to be caused to revolve with the shaft Dby means of asuitable clutch-collar, f, moving on a spline or feat-herof the shaft,aswill be understood. The gear-wheel E meshes with abevelpinion, 9,located on one end of a shaft, F, which has a bearing in one of the barsA of the frame, beyond which it projects to receive a crank-wheel, G.The inner portion of said shaft F is supported by means of acurved baror rail, h, which is secured to the frame, as represented in Fig. 1. Oneof the bars 13 is extended for the attachment and support of thecutter-bar guard and guide-frame. An

arm, H, is secured to the end of said bar B, so

(No model.)

as to extend at right angles therefrom, and the said arm has connectedto its outer end the guard-shoe I, which is of the peculiar formillustrated in Fig. 2. The said guard-shoe consists of a easting,or maybe made of wrought metal, and has a curved portion, j, which is providedwith perforations 70, this portion be ing adapted to receive the end ofthe bar H, and permit bolts to pass vertically therethrough and throughthe perforations 7:, thus securing the shoe on the end of the arm H. Thesaid shoe is provided centrally with a recessed portion, 1. Abar, J, hasits inner end secured by bolts to the shoe, and isintended to form aguide for the cutter-bar K. The end of said cutter-bar is enlarged atits end m, which enlargement normally occupies the recess Z of the shoe.This said enlargement is transversely perforated for the attachment ofthe bifurcated end nofa pitman-rod, L,a pivotbolt passing through saidbifurcated end and enlargement to secure the parts together. A link, 0,is connected at its upper end to the cutter-bar, while its lower end isattached to the under cutter-bar, K, a pin, 1), projectlng from its sidebeing designed to enter a bearing, q, secured on the upper face of theguardshoe.

By employing the link 0 and pin 1) asimple and effective arrangement isprovided for actuating both the upper and lower cutter-bars. It will benoticed that the perforations in the end of the link 0 are elongated, soas to allow a limited play of the cutter-bar pins therein, and effect apositive movement of said cutterbars relative to each other. The otherend of the pitman is connected to the wrist-pin by means of a verticalblock, M, having a semicircular depression on one side,a curved block,N, being similarly recessed at n to form, in conjunction with the blockM, an opening for the reception of the pin of the driving-wheel G. Thetop and bottom of the block N is grooved for the reception ofthethreaded ends 0 ofthe bifurcated portion of the pitman, the saidthreaded ends passing through horizontal perforations in the block M, sothat nut-s P can engage and retain the said ends. The connectiondescribed enables the pitman to swing on the pin of the drive-wheelduring the rotation of the same.

It will be readily seen from the foregoing the upper and lowercutter-bars to engage said 15 slots, a central pivot-pin for said link,a pitman pivotally connected to the enlarged portion of the uppercutter-bar and having its other end bifurcated and threaded, asdescribed, and bearing-blocks N M, and crank- 20 disk G, substantiallyas set forth.

In testimony whereof I affix my signature in presence of two witnesses.
